📚 Teaching Guide: Centuries and Chronology

Placing events in time is a key skill in history and social studies. This free centuries and chronology worksheet generator creates unlimited exercises to turn years into centuries, read and write Roman numerals, work out elapsed years, put events in order and mark dates on a timeline, always with a worked answer key.

🏛️ Year → century

The "hundreds + 1" rule, with the boundary years that trip pupils up: 1500 is in the 15th century and 1501 in the 16th.

🔢 Roman numerals

Converting Roman numerals to ordinary numbers and back, with century numbers and dates like the ones on monuments.

⏱️ Elapsed years

Durations between two dates, including BC to AD, remembering there is no year 0: from 50 BC to AD 50 is 99 years.

📍 Timelines

Timelines drawn to scale with century marks, to place dates and see how BC years count backwards.

🧩 Events in order

A bank of more than 90 well-known events from Prehistory to today, with a focus on Spanish and European history.

✅ Worked answer key

Every answer shows the reasoning step by step (1492 → 14 + 1 = 15 → 15th) so marking is quick and mistakes are easy to explain.

❓ Frequently Asked Questions about Centuries and Chronology

How do you work out which century a year is in?

Take the hundreds in the year and add 1: 1492 has 14 hundreds, and 14 + 1 = 15, so it is the 15th century. If the year ends in 00, the century is just the number of hundreds: 1500 is still in the 15th century.

Why are there 99 years, not 100, from 50 BC to AD 50?

Because there is no year 0: 1 BC is followed straight away by AD 1. So when two dates are on either side of that point, add them and take away 1.

Which dates mark the historical periods?

We use the conventional dates of Spanish and European history teaching: Prehistory ends around 3000 BC with writing, Ancient History ends in 476, the Middle Ages end in 1492 and the Early Modern Age ends in 1789. Since then we speak of the Contemporary Age.

Why are the centuries not in Roman numerals in English?

In English, centuries are written as ordinals (the 15th century). Roman numerals have their own exercise type, so pupils can still practise them.

Which grades are the worksheets for?

Grades 4 to 7 (ages 9 to 13). Each exercise type has three levels, and each level shows the suggested grade and the skill it builds.
